About this trial

This is an interventional basic science trial for Heart Failure

Eligibility Criteria

19 Years - 89 Years (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  1. Subjects are capable of giving informed consent.
  2. Age 19-89
  3. Diagnosis of chronic heart failure
  4. Any patients scheduled for at least one of the following procedures:

    1. LVAD implantation or as recipient for cardiac transplantation.
    2. LVAD placement both as bridge to transplant and as destination therapy.
    3. LVAD explantation
    4. Valve replacement or repair
    5. Catheterization and myocardial biopsy for idiopathic cardiomyopathy
    6. Coronary artery bypass graft (CABG)

Exclusion Criteria:

  1. Life expectancy less than 2 weeks
  2. Diagnosed with following co-morbidities: cancer, chronic kidney disease (GFR≤30 or serum creatinine >2.1), active infection or treatment with antibiotics or persistent infectious disease (hepatitis, HIV, etc), cirrhosis, active substance abuse and/or alcohol dependence (≥ 14 alcoholic beverages per week).

Control Myocardial Tissue from Donor Hearts Inclusion Criteria

  1. Samples collected from non-failing hearts deemed unsuitable for transplantation by TransLife because of either acute recipient issues or post-harvest evidence of pathology or positive but benign serology.
  2. Normal cardiac function from medical records

Exclusion Criteria:

  1. Pathological remodeling and extensive infarction with limited non-pathological regions of myocardium.
  2. Abnormal or impaired cardiac function from medical records, which are self determinants for rejection as a donor organ.

Arms of the Study

Arm 1

Arm Type

Other

Arm Label

Cardiac surgery

Arm Description

Subjects will be recruited by a coordinator through electronic medical record (EMR) searches to identify those undergoing left ventricle assist device (LVAD) implantation and explantation, heart transplant, valve replacement or repair, endomyocardial biopsy during catheterization, and arterial bypass surgery. Prior to the procedure, potential subjects will be informed about the clinical study and if interested, they will be consented.

Outcomes

Primary Outcome Measures

Analyses of collected tissues
Tissue samples collected during surgery will be analyzed by way of immunoblot and qrtPCR of mRNA for metabolic enzymes on neutralized acid extracts.
